Geosphere Review

1. type of rock formed from the compaction of sediment
5. type of physical weathering where pressure changes cause a rock to break into sheets
7. movement of sediment
8. type of physical weathering where a rock cracks due to heating up and cooling down
10. fossil fuel formed from plants like ferns
11. will break rocks physically without changing the rocks chemistry
12. sulfur and nitrogen mix with water in the atmosphere and rain down
13. chemical weathering where oxygen reacts with iron forming rust
15. physical weathering where a substance gets into a crack in a rock and breaks it apart
16. type of rock formed through heat and pressure
17. type of chemical weathering where a rock absorbs water and becomes soft

2. when sediment is dropped into a new location
3. type of chemical weathering where carbonic acid and groundwater react to form caves
4. break a rock by changing its chemistry
6. type of physical weathering where rocks or tiny particles hit against other rocks causing them to smooth
9. breaking of rock into sediment
14. type of rock most resistant to weathering
